Definitions

  • the present invention relates to a gearbox operating unit for commercial vehicles, of the type including a pair of operating levers connected together with the interposition of a joint and articulated with the structure of the vehicle by means of a connecting rod.
  • the use of two operating levers for connecting the manual gear lever to the selector of the gearbox results both from the exigencies of bulk and the need to facilitate the tilting of the cab when it is necessary to work on the engine.
  • the current solution provides for the use of a first operating lever terminating at the selector and provided, close to the universal joint connecting it to the second lever, with a ball joint connected to a connecting rod articulated with the power unit.
  • the use of such a connecting rod is necessary in order to enable the transmission both of rotational movements coaxial with the levers and backward and forward movements for the selection and engagement of the various ratios of the gearbox in known manner.
  • the object of the present invention is to provide an operating unit of the type specified at the beginning of the description, which does not have these disadvantages and which is simple and cheap to manufacture.
  • this object is achieved by virtue of the fact that the joint includes a central spherical member with two opposite diametral appendages which are articulated with one end of the connecting rod whereas the operating levers are articulated with the connecting rod via the spherical member in correspondence with the joint.
  • an operating unit for operating the gearbox C of a commercial vehicle is generally indicated 10 and includes first and second operating levers, 11 and 12 respectively, interposed between the selector of the gearbox C and the manual gear lever, indicated L in the drawings, located in the driving cab of the vehicle.
  • the manual gear lever L has a ball joint S housed in a spherical seat M fixed to the structure of the vehicle and a lower actuating end 13 articulated at 14 with the second operating lever 12.
  • the latter has one end 12a, opposite the end articulated with the manual gear lever L, connected by a joint 15 to one end 11a of the first operating lever 11.
  • the joint 15 is articulated with the structure A of the vehicle, in this instance the engine block, by means of a connecting rod 16.
  • the latter has a first end 16a articulated at 17 with the structure A of the vehicle about an axis X-X which is substantially perpendicular to the longitudinal axis of the engine, and a second, forked end 16b defining a pair of arms 18.
  • the joint 15 includes a fork 19 fixed to the end 11a of the first operating lever 11 and provided with two seats 19a for housing pins 20a carried by an annular member 20 coaxial with a tubular body 21.
  • the latter has ends 21a housed rotatably in bushes 22a fixed to the end 12a of the second operating lever 12 about an axis Y-Y substantially perpendicular to the lever itself.
  • the bushes 22a which in essence constitute the "fork” 22 of the second operating lever 12 corresponding to the fork 19 of the first lever 11, are spaced from each other so as to enable the annular member 20 to be housed in the space between them, coaxially with the tubular body 21 and fixed thereto during assembly by means of a threaded dowel 23.
  • the tubular body 21 and the annular member 20 fixed thereto thus constitute the "cross" of the joint 15, the arms of the cross being defined by the pins 20a connected to the annular member 20 and by the ends 21a of the tubular body 21 rotatably housed within the bushes 22a.
  • the tubular body 21 has an inner wall portion 21b shaped as a spherical seat and arranged to house a spherical member 24 having diametral appendages 24a in correspondence with which a through-hole 25 is formed.
  • the diametral appendages 24a of the spherical member 24 are substantially in contact with the arms 18 of the forked end 16b of the connecting rod 16.
  • the inner wall of the tubular body 21 also has an annular seat 26 for housing a resilient split ring 27 for retaining the spherical member 24 in its seat 21b.
  • the through-hole 25 in the spherical member 24 houses a through-pin 28 constituted, for example, by a bolt, the ends of which are inserted in suitable holes 29 formed in the arms 18 of the forked end 16b of the connecting rod 16.
  • the joint 15 is assembled by means of the insertion of the tubular body 21 coaxially in the bushes 22a after the annular member 20 has been disposed coaxially with the axis Y-Y.
  • the spherical member 24 is inserted in the tubular body 21 and is then prevented from leaving the spherical seat 21b by means of the resilient split ring 27 housed in its annular seat 26.
  • the joint 15 is then fixed to the connecting rod 16 by means of the pin 28 which passes through the hole 25 in the spherical member 24.
  • the spherical member 24 associated with its seat 21b allows the joint 15 to transmit the small rotational movements needed for the selection of the gears, indicated by the arrows R in the drawings, while fixing the joint securely to the structure of the vehicle.
  • This fixing enables "axial" movements to be transmitted, these being shown by the arrows T in the drawings.
  • the axial movements of the levers 11 and 12 drives the auxiliary lever M of the selector of the gearbox C, while the coaxial rotation R of the levers drives the further component C1 of the selector through an arm N.
  • the operating unit 10 has a single gear-selection fulcrum located in correspondence with the point H at the centre of the spherical member 24. This improves reliability, the precision of the whole operating unit, and eliminates the component forces caused by the different positions of the fulcrum relative to the centre of rotation.
